The ldns-keygen tool in ldns 1.6.x uses the current umask to set the privileges of the private key, which might allow local users to obtain the private key by reading the file.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - The ldns-keygen tool in ldns 1.6.x uses the current umask to set the privileges of the private key, which     might allow local users to obtain the private key by reading the file. (CVE-2014-3209)

Note that Nessus relies on the presence of the package as reported by the vendor.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - The ldns-keygen tool in ldns 1.6.x uses the current umask to set the privileges of the private key, which
    might allow local users to obtain the private key by reading the file. (CVE-2014-3209)

The remote Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3491-1 advisory.

    Leon Weber discovered that the ldns-keygen tool incorrectly set permissions on private keys. A local     attacker could possibly use this issue to obtain generated private keys. This issue only applied to Ubuntu     14.04 LTS. (CVE-2014-3209)

    Stephan Zeisberg discovered that ldns incorrectly handled memory when processing data. A remote attacker     could use this issue to cause ldns to crash, resulting in a denial of service, or possibly execute     arbitrary code. (CVE-2017-1000231, CVE-2017-1000232)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Updated ldns packages fix security vulnerability :

ldns-keygen creates a private key with the default permissions according to the users umask, which in most cases will cause the private key to be world-readable (CVE-2014-3209).
